338 RUM performance

Ok I've been considering a 338 caliber rifle for hunting in Alaska. Initially I was looking at the 338 win mag, after running the ballistics I really don't see the benefit over a 300 win mag. The 338 RUM looks like it would really fill the gap between those two cartridges, especially for the shots over 400 yards.
I'm considering the remington 700 XCR, does anyone have some knowledge of the accuracy potential of this rifle/cartridge combination? I'm also curious about the recoil, I like shooting magnum rounds but I've never shot a 338.
I shoot 385 grain 50. cal muzzle loader bullets behind 130 grains of powder without the slightest problem, and the 3 1/2" magnum turkey loads are not even close to being an issue. Is the 338 RUM more harsh in terms of recoil?

Brass will hold up fine if you don't push it hard. me, I push it hard so my brass doesn't last real long. Accuracy potential is very good to 1200. I am currently using 300 gr berger in front of 90 grs of h1000 with a verified velocity of 2830 and 225 accubonds with 98 grs of h1000 at 3300

I wanted a .338, but I wanted it in the Remington Sendero. I am totally sold on the Sendero as being the finest over the counter rifle built, primarily due to its full length aluminum bedding block. They are amazingly accurate right out of the box, and the improvements they made in the second generation have made them even better. I have three of them and they all are tack drivers as is the .257 STW I had one of them converted to. My problem was that Remington does not chamber their Sendero in .338. So I bought a .300 RUM, took it over to Benchmark barrels, and had the .300 barrel taken off and the .338 screwed on. (And that is all you have to do to make the change.) I added their brake, and it shoots .5 MOA groups with recoil in the .243 range. Can't beat it IMHO. I like it better than my CZ .338 Lapua.

It sounds like the accuracy is great, how's the recoil in an un-braked carry rifle (total weight about 8 1/2 pounds)?
I'm staying away from the brakes because this will be a mixed use hunting rifle, way too much noise without hearing protection!
